I got my wheels punctured twice in less than three years: you need to be street-smart and bike-street-smart in London!
If active bike thieves keep punching tyres at a sustained pace, how many bikes will they reap by so doing? How much money to bike shops, and any unintended actions there!? Enough to revive stagnating domestic demand (for tyres) in the UK? Would John Keynes agree on similar reasoning, and Mr Cameron?
